access password protection forms

HI, im trying to set up a password protection before access a Form within a MSAccess Switchboard and I found a vb code that is supposed can do it, I can send those links to anybody by requesting for more information:
this is the module:
Public MyPassword
Public Function KeyCode(Password As String) As Long
' This function will produce a unique key for the
' string that is passed in as the Password.
Dim I As Integer
Dim Hold As Long

For I = 1 To Len(Password)
Select Case (Asc(Left(Password, 1)) * I) Mod 4
Case Is = 0
Hold = Hold + (Asc(Mid(Password, I, 1)) * I)
Case Is = 1
Hold = Hold - (Asc(Mid(Password, I, 1)) * I)
Case Is = 2
Hold = Hold + (Asc(Mid(Password, I, 1)) * _
(I - Asc(Mid(Password, I, 1))))
Case Is = 3
Hold = Hold - (Asc(Mid(Password, I, 1)) * _
(I + Len(Password)))
End Select
Next I
KeyCode = Hold
End Function

The problem is:
1.- I have Access2003
2.- I think code have a little bug...

this is the main function wich calls the module:Private Sub Form_Open(Cancel as Integer)
Dim Hold As Variant
Dim tmpKey As Long
Dim I As Integer
Dim rs As DAO.Recordset
Dim db As DAO.Database

On Error GoTo Error_Handler
' Prompt the user for the Password.
DoCmd.OpenForm "frmPassword", acNormal, , , , acDialog
Hold = MyPassword
' Open the table that contains the password.
Set db = CurrentDb
Set rs = db.OpenRecordset("tblPassword", dbOpenTable)
rs.Index = "PrimaryKey"
rs.Seek "=", Me.Name
If rs.NoMatch Then
MsgBox "Sorry cannot find password information. Try Again"
Cancel = -1
Else
' Test to see if the key generated matches the key in
' the table; if there is not a match, stop the form
' from opening.
If Not (rs![keycode] = KeyCode(Cstr(Hold))) Then
MsgBox "Sorry you entered the wrong password." & _
"Try again.", vbOKOnly, "Incorrect Password"
Cancel = -1
End If
End If
rs.Close
db.Close
Exit Sub

Error_Handler:
MsgBox Err.Description, vbOKOnly, "Error #" & Err.Number
Exit Sub
End Sub

I think the code breaks in this certain line... but Im really novice with vb...
If Not (rs![KeyCode] = KeyCode(CStr(Hold)))

any help will be apreciated...

Thanks In Advance
